@tangodancer I had a half dose the first month only, and then a full dose for eleven months. I don't know of any studies on the efficacy of Evenity at a lower dose, but there have been studies regarding the timing of peak effects. If someone experiences intolerable side effects, they stop the treatment rather than lower the dose. Only the full dose of Evenity is FDA approved, and the data is based on the full dose. It's worth noting that Evenity is not a one and done treatment for osteoporosis. It needs to be followed by another drug to lock in your gains. It's imperative that patients discuss the long-term plan with their doctor prior to starting medication.
In general, people are going to report the negative rather than the positive. It's good to be well-informed, but it's not healthy to be fearful so I always report the positive experiences I've had. For the record, I've done Fosamax, Evenity, Tymlos and Reclast. Best wishes to you!
